Colin Garrett is a genius and an agent for Agency Zero.
When his parents, both with genius IQ's, decided to have a child, they also decided to create the smartest person in the world. From before he was born, Colin Garrett was exposed to the greatest minds available and he responded even faster than any one could have predicted.
Reading by two and analyzing complex problems by three, Colin showed that he had a photographic memory and a computer-like logical approach to everything. He also showed that his brain was capable of phenomenal feats. He also learned that when pressed to extremes, his eyes changed color and literally glowed with a green tint.
After his parents were killed when he was a young teenager, Colin grew tired of being the object of attention and fear and quickly learned how to 'dumb down' to fit in with normal people. He allowed his full potential to come out only when it was vital - to himself or to his country.
Content to operate as a one-man management consultancy, Garrett works when he needs the money and plays when he can. Virtually no one in his small world of acquaintances know the extent of his abilities. They simply know that he is incredibly smart and insightful.
On the other hand, Garrett is also mechanically inept. He hates cars, distrusts planes, and has little good to say about any electrical device, all because he is capable of ruining anything he makes the mistake of touching. As one close friend pointed out, Garret could easily draw the schematic of any television set but could blow it by just touching a knob.
And with all that, he is on call for the secret bureau called Agency Zero.
